Bingo flash board for iPad or mac

[Artaxx]

I'm looking for a bingo app or a program that will just serve as the flash board and not generate the numbers. We have someone to pull the numbers, I just need to project the numbers called on a screen. Does anything like that exist? Looking for iPad or Mac compatible. I found bingo and bino machine, but they dont allow for manual input of the numbers called. Thanks in advance for your help!
